Imported orders date and time error

Hello!
I used the plugin to export and import Woocommerce Orders from one store to another. I imported 100 orders from last month into my new store. In this new store, I have set up a follow-up email for all customers who have made a purchase 2 weeks ago.

So there is a problem that all follow-up emails are sent to customers at the same time, 2 weeks after the import has been done. It seems that the follow-up plugin starts counting time after the import is done, not from the actual order date. Why is that so? Is it possible to override the orders date with actual data?
